program.
When the switch is set to AUTO, the relay functions as programmed.
Setting the switch to OFF does not activate the relay.
The switchover is possible per channel.
6.9. Using the MANUAL Keys
Use the MANUAL keys (front-mounted) to activate the output relay regardless of the timer program.
Pressing the key causes the output relay to close for 5 seconds. This is possible for each individual output.
Use the keys when performing a test at time of equipment installation or for other purposes that necessitate
the manual relay activation regardless of the timer program.
Note
These keys do not work during power outage.
These keys work regardless of the front-mounted AUTO/OFF switch setting.
13
6.10. Using the CHANNEL ASSIGNMENT Switch
The CHANNEL ASSIGNMENT switch (rear-mounted) is used to switch over from the B, C or D channel to the
A channel.
When the B channel switch is set to ON, the B program output is delivered from the A channel, with the A
program output delivered from the A channel. In this event, no output is delivered from the B channel.
[Example 1]
Given that each of the output channels is programmed as Example 1,
the output is delivered from each channel as follows.
If all the switches are set to OFF.
A channel: Output is delivered at 8:30, 9:30 and 10:30.
B channel: Output is delivered at 9:00, 10:00 and 11:00.
C channel: Output is delivered at 12:00.
If both the B and C switches are set to ON.
A channel: Output is delivered at 8:30, 9:00, 9:30, 10:00, 10:30, 11:00, and 12:00.
No output is delivered from both the B and C channels.
6.10.1. The CHANNEL ASSIGNMENT switch vs. AUTO/OFF switches
The AUTO/OFF switches (front-mounted) are effective for the program registered into each output.
If the CHANNEL ASSIGNMENT switch of B channel is set to ON and the AUTO/OFF switch of A channel to
OFF in Example 1.
A channel delivers output at 9:00, 10:00 and 11:00.
B channel delivers no output.
C channel delivers output at 12:00.
Tips
• Since the A AUTO/OFF switch is set to OFF, the output is not delivered from the A channel at 8:30, 9:30 and
10:30 as programmed.
• Since the B channel is switched over to the A channel, the A channel delivers output at 9:00, 10:00 and
11:00, the times programmed into the B channel.
If the A channel MANUAL key is pressed under these conditions, the A output relay makes for 5 seconds.
Pressing the B channel MANUAL key causes the A channel relay to close for 5 seconds because the B output
is switched over to the A channel.

6.10.2. Use the CHANNEL ASSIGNMENT switch in such cases as shown below:
(1) To allow one single equipment to process four different programs through combined use of the CHANNEL
ASSIGNMENT switch (rear-mounted) and the AUTO/OFF switch (front-mounted).
When, for example, the school has the Westminster chime and they want to utilize it for the following four
different programs.
1) Ordinary school hour program (Monday to Friday)
2) Saturday program
3) Temporary shorter school hour program
4) Examination day program
1) Register the ordinary school hour program into the A channel. (Register Monday through Friday.)
2) Register the Saturday program into the B channel. (Register Saturday.)
3) Register the temporary shorter school hour program into the C channel. (Register Monday through
Saturday.)
4) Register the examination day program into the D channel. (Register Monday through Saturday.)
Set the CHANNEL ASSIGNMENT switches B, C and D to ON.
1) To operate the ordinary school hour program and Saturday program
Set the AUTO/OFF switch to AUTO for the A and B channels, and to OFF for the C
and D channels. This allows the ordinary school hour program to be operated on
Monday through Friday, and the Saturday program on Saturday.
2) To operate the shorter school hour program
Set the AUTO/OFF switch of the C channel to AUTO, and those of other channels
to OFF.
3) To operate the examination day program
Set the AUTO/OFF switch of the D channel to AUTO, and those of other channels
to OFF.
Thus, by shifting the AUTO/OFF switches different programs can be readily operated.

6.11. Points to Remember
• All the indications go out at time of power outage. However, a clock works normally and stored programs are
maintained. No relay output is produced. After power restoration, the timer works normally and indicates the
current time.
• A clock and stored programs are maintained for about 100 hours during power outage.
If the clock display flashes to indicate “0000” with beep after power restoration, this indicates that the battery
has run down. In such a case, set a clock for the current time and register the program again.
• The 100-hour power outage protection is subject to the battery being kept fully charged. It takes about 200
hours to fully charge the battery. Frequent occurrence of power outage shortens the 100-hour protection
time.
6.12. Output Relay
• Output is a no-voltage (dry) make contact.
• The relay contact closes for 5 seconds at preset time (pulse output system).
• Output relay contact capacity: Maximum: 24 V DC, 0.5 A (resistance load)
Minimum: 10 mV DC, 10μA

(2) If exceeding per-channel program capacity of 30.
When, for example, a frequently-used spot announcing machine needs to be activated 80 times a day.
Set the CHANNEL ASSIGNMENT switches (rear-mounted) of both B and C
channels to ON.
Set the AUTO/OFF switches (front-mounted) of A, B, and C channels to AUTO and
that of D channel to OFF.
This expands a program capacity to 80, with 30 being programmable into A channel, another 30 into B
channel and 20 into C channel.
